RICHARD ALEXANDER-EAW, or BERLIN, eERMANi-h SEPARATOR FOR ELECTRIC ACCUiVlULATOR-PLATES.

SPECIFICATION forming part of Letters Patent No. 705,630, dated July 29, 1902.

Application led October 18, 1901. Serial No. 79,185. (No model.)

To all whom t pta/y concern:

Be it known that I, RICHARD ALEXANDER- KATZ, a subject of the German Emperor, residing and having my post-office address at Leipzigerstrasse 19, Berlin, Germany, have invented certain new and useful Improvements in Separators for Electric Accumulator- Plates, of which the following is a specification.

This invention relates to a separator for the' plates of electric accumulators, and is intended to provide a removable separatorwhich shall allow circulation of the electrolyte and disengagement of gases, as well as act to support the negative and positive plates and the surfaces thereof.

In the annexed drawings, Figure lis an elevation of said separator. Fig. 2 is a crosssection thereof on line 2 2. Fig. 3 is a crosssection thereof on line 3 3.

The separator consists of marginal bars f f'f2 f3 and two wde-meshed gratings g h, so located with regard to one another that the intersections of the bars of the one grating cross the open spaces of the other grating. The exterior surface of each grating is plane `and flush with the edges of the marginalbars.

V"or some of them, more particularly of the side bars f f', and the interior surfaces of the gratings are also preferably both in the plane of contact of the gratings one with the other. The gratings are preferably integral with one another and with the marginal bars, being made in one piece of a suitable non-conductive material of lightweight, such as caoutf chouc or celluloid. The top and bottom bars f2f3 are for the Whole or some part of their length of less thickness, as at 79.710', to allow space for disengagement of gases and circulation of electrolyte, and the side bars ff areA preferably prolonged downwardly for a short distance below the bottom bar f3 to form feet, as at f4, on which the separator stands when in position in the cell.

It will be seen from the foregoing description and illustration that there is ample and substantial equal passage for the electrolyte vertically and horizontally at all parts of the separator and that the surfaces of the separator which come in contact with the l surfaces of the plates of the cell support the latter along numerous uninterrupted lines, theV plane and flush with surfaces of the marginal bars.

3. A non-conducting separator for electric accumulator-plates comprising in combina- .tion two wide-meshed gratings, whereof the intersections of the one cross the open spaces of the other, the outer edges of said grat- -i-ngs all being in the same plane, and being made integral with one another.

4. A non-conducting separator for electric accumulator-plates"comprising in combination marginal bars and two wide-meshed gratings whereof the intersections of the one cross the open spaces of the other, the outer edges of said gratings all being in the same plane and'iiush withsurfaces of the marginal bars, and being made integral with one another andwith the marginal bars.

5. A non-conducting separator for electric accumulator-plates comprising in combination two wide-meshed gratings, whereof the intersections ,of the one cross the open spaces of the other, the outer edges of said gratings allbeing in the same plane, and terminating at their meeting surface in a plane.

6. A non-conducting separator for electric accumulator-plates comprising in combination marginal bars and two wide-meshed gratings whereof the intersections of the one cross `the`open spaces of the other, the outer edges of said gratings all being in the same plane and flush with surfaces of the marginal bars, and terminating at their meeting surfaces in a plane bisecting said marginal bars.

In witness whereof I havesigned" this specification in the presence of two witnesses.

RICHARD ALEXANDER-KATZ.
